FIRE-ESCAPE.

SPECIFICATION forming part of Letters Patent No. 736,056, dated August 11, 190%.

Application filed April 13,1903. Serial No. 152,291. (No model.)

To a. whom it may concern..-

Be it known that I, EDUARD BANHAGEL, a citizen of the United States, residing at Ionia, in the county of Ionia and State of Michigan, have invented certain new and useful ImprovementsinFire-Escapes; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in fire-escapes; and the purpose of the same is to produce a safe and rapid means of exit for a person, persons, or freight from a burning building, one which consists of simple means for operating the device either from the interior of the building through the windowopening or from the platform of the car or the ground, also one which may be used as an elevator for the use of firemen or the bandling of freight either ascending or descend ing, one which is adapted to ascend of its own motion by the means therein employed and to descend by means of the weight of an' object which is placed upon it, also one which is adapted to be adjusted to a plumb position whether the outside wall of abuilding to which it is adjustably attached be plumb or otherwise; and the object of my invention is to provide a device which is simple in its construction, consisting of but few parts, being light but strong as compared with its length and breadth, and which may be easily and cheaply manufactured; and, furthermore, it consists in the construction and arrangement of its parts, which will be more fully hereinafter described, and definitely pointed out in the claims. I attain these objects by means of the mechanism herein described, and illustrated by the accompanying drawings, in which- Figure 1 isa front elevation of my improved fire-escape, showing a portion of its parts as being in section in order to disclose more fully the means by which the car of the same is operated. Fig. 2 isa longitudinalvertical section of the same, taken on the line 00 a; of Fig. 1. Fig. 3is adetail perspective view of one of my improved supporting-plates shown as having been detached from its shaft. Fig. 4 is an enlarged plan view of my improved fire-escape shown in detail to more fully illustrate its operating mechanism. Fig. 5 is an enlarged front view of my improved brake mechanism shown in detail as being attached to the upper portion of the shaft,

D D D D D D are oblong plates havingholes E E E E through their centers, their ends being provided with round long threaded lugs F F F F F F. Said plates D D D D are secured to the under and upper side of the overlapping end portions B B B B, their holes E E E E being of the same diameter as the holes 0 O O O in said overlapping end portions B B B B.

G G'are plates similar in construction to plates D D D D and are secured to the perpendicular walls of the oblong shaft A about midway the under and upper side portion of the overlapping ends B B B B.

H and H are pipes, which are of the same outside diameter as the holes E E E E in the oblong plates D D D D and holes 0 O O C in the overlapping end portions B B B B, also in the oblong plates G G, through which they extend in an upright or perpendicular posi-' tion. They are placed in sections one above another and are secured by means of nuts I and I, threaded collars J and J, and nuts K and K.

it and the elongated face-plates L L L, andare held in place by the nuts N N N N N N on the outside andnuts O O O O O O, countersunk in the inner portion of said wall M.

a a a a 0; ct are angular braces, one of the ends of which is secured to the edges of the oblong plates D D D D and G' G by means of bolts inserted therein and the opposite ends to the front face of the elongated face-plates L L L by the same means. The purpose of said braces a Ct a a. a Ob is to hold the perpendicular oblong shaft in a rigid position and prevent the same from vibrating when the car of the device is in motion, which car is of ordinary construction, consisting of a platform b, with side walls 0 and c, said side walls 0 and 0 being connected at their tops by means of a cross-beam d, said car being interposed between the inner surfaces of the perpendicular walls of the perpendicular oblong shaft A and is held in place by means of tongues e e e e and grooves f and f, which grooves are formed by the perpendicular strips g g g g and extend longitudinally with the walls of the perpendicular oblong shaft A midway their outer edges, two of said tongues e 6 being interposed within the groovesf and f, opposite the platform b, and two at the top of the side walls 0 and c, opposite the ends of the cross beani d.

Referring to Figs. 1 and 4,71 and h are grooved pulleys having projecting shaft ends which are supported in standardst' Mi at the upper portions of the same, said standards 01 z' '5 7. being secured to the upper surface of the perpendicular oblong shaft A by means of bolts inserted therein. Said grooved pulleys h and h have their outer surfaces in perpendicular alinement and parallel to the perpendicular front surface of the perpendicular oblong shaft A. t

j and j are standards secured to the upper horizontal surface of the perpendicular oblong shaft A, midway the outer perpendicular surfaces of said perpendicular oblong 'shaft A, by means of bolts inserted therein.

7; is a standard of similar construction, which is secured to an angular plate 1, abutting the upper edge of one of the elongated faceplates L by means of bolts inserted therein. A shaft m is mounted within said standards j, j, and at their upper end portions. Directly underneath the angular plate I and standard 7c is an angular plate n and standard 0 of similar construction,'said angular plate at having its outer surface abutting the lower edge of the elongated face-plate L, which is directly opposite the lower horizontal portion of the perpendicular oblong shaft A.

Mounted upon the shaft m near the standard 7c is a large grooved pulley p. Directly underneath said grooved pulley p is another pulley q of similar construction and of the same diameter, which is mounted on a shaft 1', supported in the standard 0. Said shaft 1' is fixedly secured to the angular plate 11 and outside wall M of the building by means of bolts inserted therein.

sis an endless cable extending over pulleysp and (1 through elongated slots tand it, formed in the horizontal portions of the standards 7t and o and angular plates land 77..

Mounted on the shaft 121 between the upright portions of the standards j and j is a drum U, having triple flanges formed therewith, one on each outer surface and one in the center thereof.

Q) and 'u'are cables which are wound around the drum U in opposite directions, one from the upper side and the other from the under side thereof, and they are separated from each other by means of a flange in the center of said drum. U, the purpose of which is to prevent the cables '0 and o rubbing against each other and also to prevent unnecessary friction against the flanges of the grooved pulleys h and h, which would otherwise be when they are in motion should two separate drums with double flanges be used instead of one with three flanges, as shown and described. The ends of the cables 1; and 1; extend downward through an elongated slot if in the upper portion of the perpendicularoblong shaft A and are secured to the tops of the walls 0 and c of the car. The opposite ends of said cables v and o extend over the grooved pulleys h and h and are secured to weights w and w within the pipes H and H, said weights to and 10 serving the purpose for elevating the car to the upper portion of the perpendicular oblong shaft A.

y is a hand-wheel having a threaded shaft 3 Which extends through the wall 0 of the car opposite the grooves f. It is adapted to regulate the speed of the car while it is descending.

Referring to Fig. 5, my improved brake mechanism consists of a curved arm 1, pivotally secured within a forked standard 2, secured to the uppersurface of one of the overlapping portions B of the perpendicular oblong shaft A by means of aclevis 3 and nuts 4: and 5. 6 is a curved spring secured to the under side of the curved arm 1 and the upper surface of the perpendicular oblong shaft A by means of bolts inserted therein. 7 is a curved groove formed in the under side of the curved arm 1 near its outer end, said curved portion being of the same contour as the outer circumferential surface of the wheel 8, which is mounted upon the shaft m directly underneath it. The purpose of the groove 7is to prevent the curved arm 1 springing sidewise when in frictional contact with the wheel 8. At the outer free end of the curved arm 1 a cable 9 is secured, which extends downward through holes 10 and 11 in A by means of nuts let let and 15 15.

A suitable covering or housing should be provided to protect the working parts of the device; but it was thought to be unnecessary to show one in the drawings, as it would not be considered a part of my invention.

To operate the car from an upper story of a building, it will be necessary to see that the shaft 11 at the center of the hand-wheel y is turned up tight against the perpendicular surface of the groove f until a person has stepped upon the platform I) and is ready to descend, when the hand-Wheel y is gradually turned in the opposite direction until the requisite speed is attained. The car may be quickly stopped at any portion of its upward flight by pulling down on the cable 9, which brings the curved arm 1 in frictional contact with the wheel 8, mounted on the shaft m. It will be readily understood that the car will only be elevated when used as an elevator, when the weights to and w are heavier than the objects placed therein, without pulling down hand over hand on the endless cable 8.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
